RE: Allison MD3060 shut down
I have the exact same problem with my MD3060 ECU (1994 Fleetwoot 5.9 Cummins) It goes completely dead when it's cold. I am able to reproduce the problem on demand by placing the ECU in the freezer for 5 min. It goes dead then I heat it with a hair dryer for about 5 min. and it comes back alive!
The sad part is I went to an Allison repair shop and they said it was $2500.00 for the ECU and $1500.00 for the control panel. $4000.00 and that's remanufactured with my exchanged unit. Ouch!
I searched information for several days on the net and I just happen to stumble upon one lone post with no replies. The guy said...."Allison ECU's repaired on the cheap.....under $500.00" and gave the web address for the company. I checked their site and they are an actual Allison approved repair facility. I called and they said it's a $370.00 flat rate repair for those ECU's. Wow what luck. I even talked to the repair tech and he sounds very confident in repairing my issue.
I have spent hours trying to find that lone post that tipped me off for this affordable repair service. I wanted to thank the guy for literally saving me thousands. I can't find it any where. It was on some RV forum I think.
My ECU is at DMR electronics right now being repaired (I hope).
www.DMRElectronics.com The ECU is actually called a WTEC-II controller. I hope this helps someone else.
